Create Stuff 'N Additions x Sable & Aeronautics Compat

The add-on lets the Create Stuff 'N Additions content work on moving sublevels from the Sable and Aeronautics stack. Its features cover the jetpack floor detection, the grappling item that hooks onto sublevels, and the Block Picker, which moves blocks between sublevels and the main level. It also patches a few bugs, including one where a block's data could be lost when block entities were selected with the Block Picker disabled.

Two other behaviors are set through the common config: the netherite jetpack exoskeleton can hide its first-person view, and the grappling item can be used in the offhand, though it cannot create two chains at the same time. The last version depends on Create Stuff 'N Additions 2.1.3 and on Sable, which is required as well. The add-on runs on client and server, so both sides need it, and it is published for NeoForge 1.21.1 only. The code is not open source, and it is released under All rights reserved.
